Demonstration of afforestation for control of sand drift along base highway oil field in hinterland of Taklimakan Desert—A study on irrigation technology of saline water at sandy strata

摘要

Research was conducted on different ways of irrigation system, distribution and dynamic trend of water and salt in soil irrigated by saline water so that we initially grasp their laws, and supply scientific gist to decide on irrigation ways and system. The results show that drip irrigation can be chosen during construction of plant sand control system firstly in the hinterland of desert. In plain sand, furrow irrigation and surveying water by pipeline can also be utilized. We should adopt the irrigation system, with irrigation interval of 20d and irrigation quantity of 30 kg per square meter, when we utilize drip irrigation system to build shelter-belt in the hinterland of Taklimakan Desert watered by saline water.
